I do not know if your CoconutBattery is doing that but the numbers do not make sense at all. Can you look under About this Mac -> More Info -> System report -> Power and get the battery numbers from there. What you showing here is a old battery, that has already seen over half of its life but it shows only 86 load cycles--- which is not possible/correct. ...

According to Everymac's MacBook Pro listing, there is no such thing1 as a MacBook Pro 13" Late 2008 5,1. The earliest 13" MacBook Pro was a June [Mid] 2009 5,5. The smallest Late 2008 5,1 model was only 15". To clear things up: Maybe you mean MacBook and not MacBook Pro? Is it a Unibody model, or Pre-Unibody? Is it really a 13" or 15"? Is your battery ...

For some operations certain models require more power than the Power Supply alone can deliver at a given time. For this incident it relies on additional power from the battery. It is to be assumed that that is your machines issue. You'll probably need to get that battery replaced. The price is usually between 120-150 at an Apple Certified Repair Center in ...

Lots of good advice here about reducing power usage and checking what's currently using it, but nobody has suggested replacing the battery. They just don't have as much capacity now as when they were manufactured. It isn't too difficult to do with the right tools, though if you aren't comfortable with the risk of breaking the phone you can pay someone to do ...

I had similar problem, where the battery was showing as not existing. Took it to the Apple Store, and their tests showed no battery, which confused them. They took it in the back and returned a few mins later. It was the battery power meter on the side of the MacBook Pro, you know the one that lights up with 6 tiny white lights? The battery pack is ...

Possible bad news, you should have gotten Replace Battery warnings way before, that you could not missed. What it indicates is your Logic board is failing where the SMC chip sits on it. You can open it and take battery out, then place it back in, but that is slim hope. Before you spend a fortune in replacing the logic board: There is a small circuit build ...

Unfortunately I can't see the image you posted right now (due to proxy filtering) but if it says "Service Battery" you can either live with it or buy a new battery. Chances are the battery's integrated status monitor is either correctly identifying a battery failure or the the monitor itself has failed. There isn't a "fix" for this other than replacement. If ...

You probably knocked the battery connector out. Here's a link to a repair guide to replacing the whole battery, which is more than you need. Do steps 1 and 2 to open your computer up, and then make sure the battery connector in Step 3 is 100% plugged in. If it's fully plugged in and it's still not working, the battery itself is probably shot.

A simple answer, start the MacBook and hold down the D key when you hear the startup chime. This will start the built-in diagnostics and any problems that are found will be listed here. Apple link here.

Follow those instructions for single-user-mode, then when you are done, type "exit" and copy some of the first few lines of the output - on paper if you need to. I'm mentioning this because I skipped the exit step a few times, but more interesting things might come up there. When I brought the lines with me and showed them to the Apple tech (genius) he ...

Yosemite startup hanging at 50% is something we've seen a good few times, and a couple of users got so fed up with it being a recurring issue they asked for a roll-back to Mavericks. The first thing to try is boot into single-user mode (Command + s at startup) and run a disk check with the command /sbin/fsck -fy. Once that's done try starting in Safe Boot ...

It could be the phone hardware is not recognizing the battery capacity correctly. Back up your phone to a computer. Do not only a factory reset but after that plug your phone back in to iTunes and act like you're going to reboot your phone while hooked up to iTunes. Once you see the Apple appear let go of the lock button but continue to hold the home ...

Apple tells me that my battery had (physically) expanded which, as I understand it, causes the machine to stop using it as a safety precaution. I had the battery replaced which cost me $250 plus labor.

Well, I'll provide an answer to my own question, tested on Yosemite but not extensively. This is bash code: #!/bin/bash humantime () { printf -v $1 "%dh%02dm%02ds" $(($2/3600)) $((($2/60)%60)) $(($2%60)); } #unplugged=`pmset -g log | grep 'Summary- \[System: DeclUser.*\] Using Batt' | tail -1 | cut -f1,2 -d' '` unplugged=`syslog -u -k Sender loginwindow | ...

I do not know of any software solution, but there is a hardware solution. Use a piece of tape and cover the middle pin on the Magsafe plug.

You are seeing the (very obvious) low-battery indicator. The battery does not have enough power to boot the device. A first-generation iPad is at least 4 years old - if it has been used regularly the battery has likely done enough cycles that it needs to be replaced. If it has been left on the shelf for extended periods the battery has discharged itself - ...

All iOS devices do that after they have been completely discharged. If it does not boot up with in 5-10 minutes of being plugged in, then it could be an indication of hardware failure. The battery is likely not accepting a charge.

Here you find an extensive list with various links to AHT images. The direct links to the AHT of your model are: 13" MacBookAir3,2 or 11" MacBookAir3,1. To copy the .diagnostics folder, mount the dmg and enter for the MacBookAir3,2 AHT: sudo cp -R /Volumes/AHTBOne/System/Library/CoreServices/.diagnostics /System/Library/CoreServices or for the ...

Your AHT feature will have been lost when you upgraded to Yosemite. You can restore it by inserting the Applications Install disc that was supplied with your computer and typing the following command, putting in the actual name of the disc where indicated... sudo cp -R /Volumes/[name of disc]/System/Library/CoreServices/.diagnostics ...

Either you're using your laptop heavily or you need to upgrade your charger with higher power (e.g. from 65Watt to 85Watt) so it can charge faster. This usually happens when you take/borrow charger from other MacBook Air and you'll try to charge your MacBook Pro (which could have Core i7 instead of i5). You can click on Battery icon to see which apps are ...

There's also an app designed to test your battery: http://batteryscore.com/ https://itunes.apple.com/app/batteryscore-easy-way-to-benchmark/id793023941?ls=1&mt=8 The score it gives isn't the easiest to interpret, but you can compare it against other scores.

When your phone is near-dead, go to Settings > General > Usage and see how long your battery has lasted. Then check how long your phone should have lasted. I use the app "System Status" by Jiri Techet to tell me that information, but you can look it up online or use another app.

So the gel containing battery acid has leaked out and dried up. You need to make it muddy again to be able to remove it, since dry removal is not possible. There are multiple methods to do that described here. (Vinegar, Lemon juice, and others). Example: Mix water and baking soda into a thick paste. Start with about a teaspoon of baking soda and add ...
